Liquid Cooling System
NOTE: Debris in the engine com-
partment or packed between the cool-
ing fins of the radiator can reduce
cooling capability. Using a garden
hose, wash the radiator to remove
any debris preventing air flow.
The cooling system capacity can be found
in the specification charts. The cooling sys-
tem should be inspected daily for leakage
and damage. If leakage or damage is
detected, take the vehicle to an authorized
Toro ROV dealer for service. Also, the
coolant level should be checked periodi-
cally.
NOTE: High engine RPM, low vehi-
cle speed, or heavy load can raise
engine
temperature.
Decreasing
engine RPM, reducing load, and
selecting an appropriate transmis-
sion gear can lower the temperature.
When filling the cooling system, use a
coolant/water mixture which will satisfy
the coldest anticipated weather conditions
of the area in accordance with the coolant
manufacturer’s recommendations.
NOTE: Use a good quality, biode-
gradable glycol-based, automotive-
type antifreeze.
While the cooling system is being filled,
air pockets may develop; therefore,
remove the bleed plug on the coolant
pipe at the front of the engine allowing
trapped air to escape.
TC024A
When pure coolant (no air) flows from
the bleed hole, install the bleed plug,
tighten securely, and then fill the cooling
system to the bottom of the stand pipe in
the radiator neck. After operating the
vehicle for the initial 5-10 minutes, stop
the engine, allow the engine to cool
down, and check the coolant level. Add
coolant as necessary.
Shock Absorbers
Each shock absorber should be visibly
checked weekly for excessive fluid leak-
age (some seal leakage may be observed
but it does not indicate the shock is in
need of replacement), cracks or breaks in
the lower case, or a bent shock rod. If any
one of these conditions is detected,
replacement is necessary.
NOTE: When the vehicle is oper-
ated in extremely cold weather (-23°C/
-10°F or colder), a small amount of
leakage may be present. Unless the
leakage is excessive, replacement is
not necessary.
This vehicle is equipped with adjustable
shock absorbers in the front and rear to
allow for different driving and loading
conditions.
The front shock absorbers (700) or front
and rear shock absorbers (500) have an
adjustment sleeve with five preload
adjustment positions that can be turned
with a special spanner wrench to increase
or decrease coil spring tension.
CAUTION
Do not use a pressure washer to clean
the radiator core. The pressure may
bend
or
flatten
the
fins
causing
restricted air flow, and electrical com-
ponents on the radiator could be dam-
aged. Use only a garden hose with
spray nozzle at normal tap pressure.
CAUTION
Continued operation of the vehicle with
high engine temperature may result in
premature wear or engine damage.
! WARNING
Never check the coolant level when
the engine is hot or the cooling sys-
tem is under pressure.
